The Penman‐Monteith equation is often used to estimate transpiration, but an important limitation to this approach, especially for mountainous forested sites, is an accurate estimate of canopy conductance averaged over the area of interest (Gs). We propose a method for estimating watershed‐scale transpiration using estimates of Gs derived from measurements...
Purpose: Primary care practices are an ideal setting for reducing national smoking rates because >70% of smokers visit their physician annually, yet smoking cessation counseling is inconsistently delivered to patients. We designed and created a novel software program for handheld computers and hypothesized that it would improve clinicians' ability to...
Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers.
Predicting plant available...

Dissolution profiles of two commercial products (Motrine and Rufen®) were analyzed and compared at 8 pH levels, ranging from pH 2.0 to pH 8.0. It was demonstrated, as expected, that the rate and extent of ibuprofen dissolution dissolution was pH dependent. In vitro dissolution characteristics of the ibuprofen solid dispersion...
Intracellular symbioses between cnidarians and dinoflagellates from the genus Symbiodinium are widespread throughout the marine environment. These associations are ecologically significant, especially in tropical waters where symbiotic interactions between corals and Symbiodinium culminate in the formation of limestone reefs. This thesis focuses on cellular and molecular aspects of the symbiosis,...
Estimates of nitrogen (N) available from long-term application of organic
amendments are required to balance N inputs with crop N requirements. Two studies
were conducted to (1) determine N mineralized from organic amendments (manures
and composts) during year 2 after application, and (2) compare plant-available N
(PAN) determined via in...
The overall focus of this thesis is on the distribution of specific lipids and membrane proteins of the external and internal membranes of plant cells, in the context of the roles that those lipids and proteins may play in microbe-plant interactions. The work includes the development of several new tools,...
The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...
